Protozoans are organisms, such as cryptosporidium, that have a life-cycle with several stages, some of which allow them to pass through a chlorine disinfection process unharmed.
A single-celled organism that is larger than bacteria.
a single-celled organism, often capable of producing disease.
A single-cell organism, usually free living but sometimes parasitic like MSX.
eukaryotic heterotroph microbe, usually motile at some stage — — CLOSE
A member of the phylum or subkingdom Protozoa, which are chiefly motile and heterotrophic unicellular protests, such as amoebas, trypanosomes, sporozoans, and paramecia.
a microscopic, one-celled organism in the Kingdom Protista
any of diverse minute acellular or unicellular organisms usually nonphotosynthetic
Single-celled organism that can perform all necessary functions of metabolism and reproduction. Some protozoa are free-living, while others, including malaria parasites, parasitize other organisms for their nutrients and life cycle.
A single-cell eukaryotic organism that is larger than a bacterium and may feed on bacteria.
Minute animals whose entire body consists only of a single cell. Protozoa is a plural word, the singular is protozoan. There are large numbers of species. Some protozoa are entomopathogens.
a unicellular member of the animal kingdom
(plural, protozoa) A protist that lives primarily by ingesting food, an animal-like mode of nutrition.
animal consisting only of one cell with a well-defined nucleus. evetment: shore protection structure made with stones laid on a sloping face.
A protozoan is a single-celled, microscopic (usually) organism. For example, an amoeba.
a one-celled animal
A single-celled animal.
an acellular or 1-celled microorganism, several of which can cause disease in humans.
A member of the Kingdom Protista. Protozoa are single-celled organisms [eukaryotes]. The single cell performs all necessary functions of metabolism and reproduction. Some protozoa are free-living, while others, including malaria parasites, depend on other organisms for their nutrients and life cycle. Malaria parasites are members of the Phylum Apicomplexa. adical Cure - treatment intended to achieve cure of P. vivax or P. malariae malaria. These two species have exoerythrocytic [outside of red blood cells i.e. in the liver] stages. Requires primaquine treatment, which destroys latent exoerythrocytic stage parasites (hypnozoites). Typical case patient: a returned traveller from Central America who has had a relapse of malaria.
Single-celled, animal-like, eukaryotic organisms of the kingdom Protista. Protozoans can occur wherever moisture exists. There are many parasites and commensals of plants and animals, as well as free-living species. They cause a number of diseases, such as African sleeping sickness, malaria, and dysentery. They are an economically and scientifically important group. It is thought that the organisms of the kingdom Animalia evolved from ancestors which were protozoans.
A single-celled, usually microscopic organism that is eukaryotic and, therefore, different from bacteria (prokaryotic).
A unicellular organism (e.g. bacteria). A metazoan is a multicellular organism.
One-celled organisms that are present in almost every kind of habitat. Some of them are disease-causing parasites of humans and domestic animals.
a microorganism in the kingdom Protozoa
Any of a large group of single-celled, usually microscopic eukaryotic organisms, such as amoebas.
Any one of a phylum or subkingdom of microscopic acellular (no-celled) or unicellular (one-celled) animals. A protozoan cyst is a protozoan in a resting stage, when it has produced a resistant cover around itself. Some protozoans are serious parasites and are classified as health-effect contaminants.
Any organims belonging to the phylum Protozoa, usually unicellular
a minute, usually single-celled, organism which does not photosynthesise. Plural is protozoa Humans as organisms
A term that refers to some 50,000 species of mobile protists.
(Plural: Protozoa) Any one of a large group of one-celled (unicellular) animals, including amoebas. They are microorganisms that differ from bacteria in that they are larger and possess a nucleus surrounded by a membrane. Several species of protozoa can be transmitted through water and cause disease in humans, including Giardia, Cryptosporidium, Cyclospora, Entamoeba and Isospora. One distinguishing characteristic of protozoa is that when released from the human body through feces they are present in an encysted (dormant) form. These cysts have a protective layer that surrounds them and keeps chemicals from penetrating them. Therefore, chlorine disinfection does not kill the protozoan cysts.
a protist with animal-like characteristics
